Ecclesiastes 2:21-24

²¹For why when another man travaileth in wisdom, and teaching, and busyness, he leaveth things gotten to an idle man; and therefore this is vanity, and great evil.

²²For why what shall it profit to a man of all his travail, and torment of spirit, with which he was tormented under the sun?

²³All his days be full of sorrows and mischiefs, and by night he resteth not in soul; and whether this is not vanity?

²⁴Whether it is not better to eat and drink, and to show to his soul the goods of his travails? and this thing is of the hand of God.
